TerraTech

TerraTech is an open-world, sandbox adventure game, where you design and build your own creations through a mix of crafting, combat & discovery. Design vehicles from a huge library of blocks. Scavenge, craft & buy new parts to survive, becoming the ultimate planetary prospector.

Once TerraTech, the current free game on the Epic Games Store, has run its course, it will be up to a yet-to-be-revealed mystery game, which will be gratis starting December 22, 2025.
